Abstract
The dispenser outlet (,) is microbiologically sealingly closeable by a valve stopple (,) which closes counter flow direction (,). Outlet,is manually reversely opened prior to the pump stroke against a spring (,). The medium reaches outlet (,) via throttles (,). Thus the medium creeps practically non-pressurized to an adhering face (,) of a droplet former (,). There the medium accumulates to a droplet suspending in the upside-down position. The medium contained in the dispenser (,) is effectively protected from germ contamination and the droplet may be simply administered to an eye or the like.
